Despite them just being stick figures, you could have chosen more appealing colors besides very bright red and blue. The joke itself wasn't very funny and the sound effects were a bit too loud. Also, for subtitles, just have them at the bottom of the screen with white text with a black stroke; much easier to read. Or you can simply color code them and then put a black stroke around them.
As for the animation itself, it's fairly simple. There were some subtle uses of tweening, which was good, but also very obvious uses of it. I will say that the blue stick man taking out the bread was a nice attention to weight since you animated his head snapping back and then forward again, giving some weight to the motion of him taking the bread besides just focusing on his hand.
Otherwise, the animation itself is lacking and needs more focus on more appealing colors, backgrounds, and content. The joke itself wasn't very funny or amusing.
